Jenna Dewan Tatum and St. Jude Children's Hospital have teamed up for a very good cause this holiday season. The Step Up star has joined forces with the hospital on its St. Jude Thanks and Giving campaign, an annual effort that encourages thankfulness during the holidays and raises money to help the hospital in the fight against childhood cancer and other life-threatening diseases. St. Jude's is proud to treat sick children without sending their families a single bill.

Now in its 13th year, St. Jude Thanks and Giving has partnered with celebrities like Tatum as well as 70 national brands to support to the cause.

"It's incredible coming here. I love coming here and working with the kids," Tatum says in a first look at her campaign video from Us Weekly. "I can't imagine a more peaceful feeling than walking into a hospital like this with your child you love more than anything in the entire world that is sick and them going, 'Don't worry about it. You don't need to worry about paying for this.'"

Dewan, who shares 3-year-old daughter Everly with husband Channing Tatum, has plenty to be thankful for herself. On Thursday, she shared Everly's adorable Christmas list on Instagram. The little one asked for everything a happy child needs, including "glitter for the fairies" and "new rocks and treasures."
